Abstract

A configuration of multiple LED modules having a plurality of LED modules that each contain a carrier that has a first main area, a second main area and at least one semiconductor layer. The first main area has a planar configuration. The LED modules also include a plurality of LED semiconductor bodies that applied on the first main area of the carrier. In addition, the multiple LED modules include a common heat sink, where the carrier of the LED modules in each case are connected to the common heat sink on the second main area.
